1. Camouflage
2. Competition
3. Competition
4. Symbiosis
<h3><u>Explanation</u>:</h3>
The camouflage is defined as the property of the living organisms that make them to prepare their body to perfectly match with their surroundings so that they cannot be recognised by their hunters. This makes them survive more in an environment with full of competition.
The competition is an interaction between the organisms where in a particular environment, different organisms compete for a particular prey for their living. Here the theory of the survival of the fittest work.
The symbiosis is an interaction between two or more species which leads to benifit of both the species in their living. Here one species help other in a form and other species do the same. There's benifit for both in the interaction.
1. Cellular respiration does not consume carbon dioxide (CO2).
Cellular respiration is a process by which plants produce energy. It consists of anaerobic (without O2) and aerobic phase(with the presence of O2). During the cellular respiration chemical energy derived from the nutrients (like glucose) is transformed into energy molecule adenosine triphosphate (ATP).
2. Unlike photosynthesis, cellular respiration occurs in all eukaryotic organisms (photosynthesis only in plants and some microorganisms). The processes of cellular respiration occur in cytosol (glycolysis) and in the mitochondrion of a cell (Krebs cycle and electron transport chain).
